GNOME print architecture - runtime files

The goals of this architecture include:

* Absolutely uncompromised output quality
* Speed, memory efficiency, and other related performance goals
* Ability to work smoothly with Postscript printers, fonts, and other
resources
* A screen display derived from the Canvas
* An extension path for a wide variety of Unicode scripts
* An extension path for a richer set of graphics operators than Postscript
supports, especially transparency
* To make life as easy as possible for application developers
